Tesla gets a patent for designing an automatic tire inflation system for its e-truck semi

Tesla has patented a new automatic tire inflation system that can adjust tire pressure in the upcoming Tesla semi-electric truck.

Shortly after the automaker unveiled the Tesla semi-electric truck – we reported that Tesla had filed for a patent on the technology in 2018.  Tesla does not specify whether it was designed for cars or trucks in a patent application, but inventor John Furtado, listed in the filing, is working on the Tesla Semi program for Tesla.

He specifically worked on the “brakes, brake controls, pneumatics, wheel ends, wheels and tires” for the Tesla Semi.  An engineer quit Tesla after he filed this patent for his former employer, Daimler Trucks, but he recently returned to Tesla.

Many military vehicles and heavy workhorse trucks use Automatic Tire Inflation Systems (ATIS) to manage tire pressure and optimize driving on different surfaces.

However, Tesla describes the “losses” of existing systems in the original patent application:

These previous solutions had several drawbacks.  With some early art techniques, the air was supplied with hollow drive axles to the fittings on its ends.  The fittings were then attached to the air intakes of the tires.  Stacked air attached to hollow drive axles to turn air into the hollow drive axles.  These fittings were subject to leakage of contaminants.  These pollutants disrupted ATIS’s operation and ultimately caused ATIS to fail.

To overcome those shortcomings, Tesla describes a more intelligent system with valves, bearings and a rotary air seal instead.

The automaker wrote in a patent application:

The automated tire inflation system (ATIS) controller for use with the vehicle in accordance with the first described embodiment, consists of controller-controlled valves, air supply inlet valves and a multitude of air outlets.  In addition, ATIS includes a channel for at least one drive axle with inner bearings and outer bearings, the channel formed in the spindle, the first hose connecting the control valve valve to the channel formed in the spindle.  Attach the channel formed in the rotary air seal and spindle between the hub, internal bearings and the outer bearings to the channel formed in the hub and the channel formed in the second hose hub to at least one wheel.

Thus, the first type of ATIS significantly reduces pollution in the ATIS air stream compared to previous ATIS systems.  Reduction in pollution extends the life span of ATIS, extends the spindle life span, extends hub lifetime and extends service cycle / tire life and extends maintenance intervals.

Here are some sketches from the full patent application:

Today, the United States Patent and Trademark Office has officially patented Tesla to its version of the ATIS system.

It is important to note that not all technologies that companies seek to secure with patents end up in commercial products.

What’s going on with the Tesla Semi?

It is reported that the Tesla Semi program has now been moved to the “limited production” stage.  This limited production is taking place in a new purpose-built building in Gigafactory Nevada, home to Tesla’s cell manufacturing.

Does the Tesla semi need a driver?

The Tesla semi-prototype has been identified as driving on a California highway, and some are speculating that there was no driver on the wheel.  While Tesla is focusing on self-driving for consumer vehicles, automakers have not focused on self-driving when it comes to its Tesla semi-electric truck project.

How much horsepower does the Tesla Semi have?

The Tesla semi, Musk says, moves in the sunlight.  The six-wheel array is powered by four independent electric motors that are powered by a battery bank at the base of the vehicle.  These are the same motors that power the Tesla Model 3, so we’re looking at a 1000 hp powertrain.
